Antique Silver Locket

I recently found a beautiful little antique piece. It’s a little silver locket necklace, it’s oval and has a starburst design on the front. I think there may be a very small gemstone in the center of the starburst but am unsure. I’ve found similar lockets online. But haven’t found any exactly like this despite my google-ing. It’s pretty enough that I am going to keep it. But I’m curious about the age/value of it. Any help would be greatly appreciated! Thanks
